This idea is great. They definitely have sibling energy going on. An AU where that challenges their relationship (or entices it) would be very interesting to see.
So I used to think Feferi and eridan were brother and sister specifically due to the slurry. However I know now that’s not the case. However I wanna write an au where trolls have siblings and stuff and I think eridan would make a good big brother to Feferi. Also incest hot
